This deck is what I'll be using at locals, since I just got back into YGO and it's cheap to build. It's fairly standardish, and it works great as it is, but nonetheless I thought I should put it up for fixes. Please make sure to read the notes at the end! Thanks.

I know that most people will jump to say "-2 Machina Soldier", but I've found him to work really well for me so I'm most likely keeping him. Also, don't bother suggesting +1 Card trooper because I don't like him.
